The lake is sparkling, several finless porpoises are swimming and playing, the shore is lush and green, and groups of egrets are looking for food.. After the Beginning of Autumn, Hengling Lake Provincial Nature Reserve, located in Xiangyin County, Yueyang City, Hunan Province, presents a vibrant scene.
Hengling Lake, located in the intersection area of South Dongting Lake and East Dongting Lake, is an important part of Dongting Lake and an important habitat, breeding ground and transit station for many rare migratory waterbirds.
"There weren't so many migratory birds to settle down before." Xia Wei, deputy director of Hengling Lake Provincial Nature Reserve Management Committee, said with emotion. In the past few years, all kinds of extensive forms of "drinking water by water" have been "growing savagely" here, destroying aquatic resources by excessive fishing, killing birds by poisonous birds, causing migratory birds to dare not inhabit, and blocking fish migration channels by illegal low enclosures. In particular, the problem of disorderly sand mining is prominent, with sand dredgers working day and night, sand and gravel yards, processing noise, sewage crossflow, and serious damage to wetland ecology.
In 2017, Hunan completely stopped sand mining in the Dongting Lake Nature Reserve, and then continued to regulate and standardize it. In 2018, Xiangyin County invested a lot of manpower and material resources, and spent half a year demolishing the low enclosure of Hengling Lake to restore the wetland ecology. "In the winter after the demolition, we welcomed more than 4400 cygnets, compared with more than 700 before.". The effect of environmental restoration has been recognized by migratory birds. Xia Wei said.
Xiangyin County launched a special campaign of "Dongting Qingbo", focusing on the clean-up of black poplars in Europe and the United States, the prohibition of fishing in rivers and lakes, the return of farmland to wetlands, the restoration of wetlands, and the crackdown on illegal hunting, so as to rectify the problems existing in Hengling Lake. It is reported that up to now, 54700 mu of European and American black poplars have been cleared, 5 sand and gravel wharf yards have been demolished, 48 dwarf enclosures have been demolished, more than 5000 mu of enclosure area has been cleared, all beaches and lakes in Hengling Lake have been cancelled, and 2 ecological dwarf enclosures have been retained as important habitats for birds to protect.
With the completion of ecological restoration projects, the once porous wetland ecosystem has been gradually improved, and Hengling Lake has been revitalized in recent years. "Before the control, there were only more than 20000 migratory birds per year, and after the control, the number of migratory birds increased significantly, reaching 340000 in recent years." Speaking of this change, Xia Wei rejoiced. The protection of migratory bird habitat
in Hengling Lake has been continuously strengthened. In 2020, Xiangyin set up the Hengling Lake Provincial Nature Reserve Management Committee to equip the reserve with a more professional management team, and the number of protection stations increased from 2 to 7. Special personnel were arranged to carry out grid management of the reserve, and patrol efforts were greatly strengthened.
"In the winter migratory season, we are on duty 24 hours a day to closely observe the arrival time, population, quantity, feeding and habitat of migratory birds." Chen Zhenhua, the stationmaster of Xinhuagou Station of Hengling Lake Provincial Nature Reserve, said that the Management Committee, in conjunction with the forest public security, formed a migratory bird protection patrol team, with the help of remote monitoring system and unmanned aerial vehicles, to form a "ground-air" three-dimensional protection mode. In recent years, rare animals such as finless porpoise and elk have been monitored many times in the
reserve. Xia Wei said: "We will continue to strengthen the protection, so that the'Migratory Bird Paradise 'has always been the name card of Hengling Lake."
